SPLASH SYSTEM F LUBRICATION.

To all whom it may concern:

Be it known that l, FRANK A. SMITH, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented a new and Implroved Oil Indicator and Distributer for t e Splash System of Lubrication, of which the following is a full, clear, and exact description.

My invention relates to an oil indicator and distributer for'the splash system of 1ubrication. An object thereof is to :provide a simple and inexpensive contrivance in which there are no movable parts, and which can be easily and quickly attached to asplash-lu bricant system at comparatively little expense and with substantially no alteration in the splash system.

A further object of the invention is to provide an oil indicator and distributer particularly ada table for the Ford cars.

With the a ove and other objects in view, the nature of which will more fully appear as the descriptioniproceeds, the invention consists in the novel construction, combination and arrangement o parts as herein fully described, illustrated and claimed.

-In the accompanying drawings, forming part of the a plication, similar characters. of reference in icate corresponding parts in all the Iviews.

Figure 1 is a fragmentary longitudinal section through a Ford car showing the engine in elevation and equipped with my oil indicator and distributer;

Fig. 2 is an enlarged vertical -section through the 'plug through which the connection between the indicator and the casing takes place;

Fig. 3 is a Fig. 2; and

Fig. 4 is a perspective view of the scoop or bafe which is to direct the lubricant to ward the indicator.

The oil 'indicator and distributer constihorizontal section on line'3--3,

tute, in reality, a bypass from the splash system of lubrication to any part of the engine casing, and in which bypass a transparent member is inte circulation of t e lubricant therethrough caused by the splash. To transform the rotary movement'of the lubricant, imparted thereto by the splash-producing means, a scoop or baille is interposed at the entrance to the bypass g' and to utilize the maximum velocity acquired by the lubricant, -the scoop is Specication o!

placed at the point where the velocity is highest, that is, substantially opposite that part of the casing where normally the lubri- -cant is contained. It therefore follows that the scoop is at the highest point of the cas- `ing where the splash-producing means are located.

The bypass is so arranged as to present a hydrostatic head of such a magnitude that a sufficient body of lubricant must be moved by the lashing means thereto before it will c ircn ate through the transparent mem ber. In consequence, a. circulation through the bypass will only take place when there is a sufficient quantity of lubricant present in the casing. Therefore there would be no, flow through the indicator when the quani tity of lubricant therein falls below a predemembers 6 which are secured y any suitable means to thedashboard 7 of the car. The upper tubular member 6 is connected'by a conduit 8 to a plug 9, which in the Ford car constitutes the magneto contact plu This is removed and in place thereof anot er plug is substituted which has a larger flan e 10. The opening 11 through which normal y the magneto contact proJects is utilized as a paage, which is in communication with the conduit 8. The contact is formed by sheet metal 12 which extends through the opening 11 to form a scoop 13 resting on the contactl 14 which leads to the coil. A ortion of the sheet me ber 12 is turned to orm a fiange 15 to rest bgtween the gasket 16 and the flange 10 of the plu 9. From this flange a contact is obtainetd by means of a stud 17 secured to theflange lOand provided ,With a knurled nut 18 by means of which a wire 19 can he secured to said stud.

The oil normally contained in the bottom 20 of the crank casing 21 is-splashed by the ilywheel and magnets secured thereto. When there is a suiiicient body of oil present in the bottom of the casingV the magnets will carry the oil on to the scoop, which will divert the flow and direct it through the passa e 11 into the conduit 8 tou-'ar the glass tue 5 The oil from the glass tube 5 may be conveyed to any part of the engine casing .by'a conduit 22. This conduit, therefore,

constitutes the distributing condu1t.

Eirperiments performed by me with the casino device have shown that 'rbc circuliiticin will take place when the engine is :it normal speed and the oil has been slightly warmed up by the working of the engine. The crunk mustcontuin a normal supply of oil and tie glass tube 5 be located in a position substantially as shown in Fig l. The circulation through the tube 5 is automatic-:illy interrupted :is the supply of lubricant in the crank casing falls below normal, thus indi cating that oil should be added to the crank casing. By lowering the tube 5 nearer to the plug 9 the circulation will coiitiuuc,'eren lifter the suppl of oil falls below normal;

but as soon as t xe supply of oil in the crank 1420.*` y From the above'description it will be seenV indicator. The onl cesinv becomcs"very'low there will be no circuliition through the tube 5 even if the tube is placed at the bottom of the dashboard.

When the oil indicator zuid distributer is to be supplied to engines-other thunthe Ford, a special connection may made to :i 5 high point of thel sphuih-producing means,

if there is no passage for a plug ns'utilieed by the ap licant in the Ford engine.

While l) have described the' principle of operation, together -with the device which I 40 now c'onsider to bethe best embodiment igaeci thereof, I desire .to buvc it understood tliut the device shown is uit-rely illuslrutive und that such cliuugesmuy be umile :is :iro wit-liin the scope of the appended claims.
